摘　　要：A novel BODIPY(boradiazaindacene) dye denoted as BODIPY-DT containing terpyridine unit has been designed and characterized.The dye is found to be selective and visual solvatochromic sensor toward DMF among test organic solvents.The sensing process displays time-controllable,dynamic signal outputs in the emission colors including red,purple,yellow and even white emission colors.It is presented that selective free radical oxidation reaction happens during the recognition process.
